BKinSD: If those groups were shot at 100 yards I would say you not only shoot well but you have found "the load" for that Rifle.
I have have been using a wonderful Remington 700 Sendero (heavy 26" barrel Varmint style stock) in caliber 270 for much of my long range Hunting for the last 21 years.
I also shoot the lethal, reliable and accurate Nosler 130 grain Ballistic Tips in it. My sight-in verification groups every year are only slightly better than your top grouping and not "quite as good" as your lower grouping (as pictured)!
I do have a Leupold 6.5x20x40mm scope (with 30m/m tube and side focus) on my Sendero.
My loading now uses H-4831SC and Federal 210 Match primers.
Enjoy that great shooting Featherweight.
Hold into the wind
